The uJVP showed an area under the curve of 0.84 in predicting an RAP greater than 10 mm Hg.Receiver-operating characteristic curves essentially describe a continuous variable (here, RAP) in terms of a dichotomy (RAP ≤10 mm Hg vs. RAP >10 mm Hg). Although this approach allows for calculation of test characteristics (in terms of sensitivity, specificity, and LRs), dichotomization of a continuous variable may result in considerable loss of clinical information ...References1.
